Pop-fusion

The mellow, bland, romantic music that came to be called "fusion jazz" in the
following decade was largely the product (a very commercial product) of
mediocre musicians such as Chuck Mangione and Al Jarreau, and of derivative
bands such as Spyro Gyra and Yellowjackets.

While not exactly fusion, a couple of innovative vocalists belonged to this
generation and brought a lot more to the "fusion" concept, besides quite
simply expanding the role of the human voice in an instrumental context.
